The speaker overall volume must be taken into account when designing a box: if the driver is mounted with its magnet facing the box inner part, add the volume indicated in the Technical Specifications (Total driver displacement) to total volume calculation. The volumes of Reflex, Asymmetric Bandpass and Double Reflex projects include tubes and ports overall dimensions.

Sealed Box 1: It optimises overall dimensions as much as possible, for those who have space problems. Sealed Box 2: It is the best compromise between size and performances; it insures powerful bass and good dynamics.
Reflex Box 1 Vb = 30 Lit Fb = 35 Hz

Reflex Box 2 Reflex Tube Ø = 85 mm L = 230 mm
Vb = 43 Lit Fb = 32 Hz
Reflex Tube Ø = 85 mm L = 230 mm
Bass Reflex 1: Its size is similar to Sealed Box 2 but it offers higher power handling and fast, wide sound. Bass Reflex 2: The best compromise between size and performances; its bass is more bursting and dynamic than the one you get with the configurations mentioned above.
Asymmetric Bandpass Vcc = 19 Lit Vb = Fb =

Asymmetric Bandpass It combines the qualities of the two previous projects with high power handling and fast, clear bass. Suitable to any kinds of music.

Double Reflex It is more difficult to build and bigger. It is the best solution to get very high SPL values and bursting, fast sound. Perfect for techno and disco music.
